Rethinking Enterprise Architecture for Sustainable Energy System Development

引用

Journal of Electronic Science and Technology 2015年第3期13卷 212-220页

作者： Jovita Vasauskaite Asif Qumer gill Kaunas University of Technology University of Technology Sydney

The development of a sustainable energy system throughout an enterprise is a complex task, which requires an agile holistic approach. Such an approach needs to include a variety of objectives including energy strategy formation and strategic decision-making, which are directly related to the analysis and management of the main areas of sustainable development： The economic, technological, environmental, and social. These multidimensional requirements of sustainability are often difficult to achieve within the enterprise, because these aspects are interrelated and influenced by various internal and external environment factors. This paper first reviews the main challenges for an energy system, and then demonstrates how a strategic agile enterprise architecture driven approach could effectively guide the sustainable energy system development. The study presented in this paper provides a holistic approach that contributes to the advancement and usage of literature dealing with issues of sustainable energy system development and agile enterprise architecture, which has not been discussed before to any great extent.

Study of obliquely propagating electron acoustic shock waves with non-extensive electron population

Plasma Science and Technology 2019年第1期21卷 29-35页

作者： Sona BANSAL Munish AGGARWAL Tarsem S gill Sikh National College Research Scholar I K Gujral Punjab Technical University Department of Applied Science Lyallpur Khalsa College of Engineering Department of Physics Guru Nanak Dev University

Obliquely propagating electron acoustic shock waves in magnetized plasma composed of stationary ions, cold and non-extensive hot electrons are investigated by deriving Korteweg–de Vries Burgers(KdVB) equation. The tangent hyperbolic method is used to solve the KdVB equation in dissipative medium. The dissipation effect is introduced in the model by means of kinematic viscosity term. The analytical calculations of the KdVB equation shows that the structures(amplitude, velocity and width) of the shock waves are modified significantly with kinematic viscosity(η_0), obliqueness(k_z) and magnetic field(ω_c). Since plasmas are ubiquitously permeated with magnetic field, it is pertinent to explore the characteristics of KdVB equation in a magnetized plasmas.

Enabling silicon photoanodes for efficient solar water splitting by electroless-deposited nickel

引用

Nano Research 2018年第6期11卷 3499-3508页

作者： Jiheng Zhao Thomas Mark gill Xiaolin Zheng Department of Mechanical Engineering Stanford University Stanford 9430S USA

Enabling Si photoanodes for efficient solar water oxidation would facilitate the development of solar fuel conversion, but it is challenging owing to Si surface passivation via photo-induced corrosion in aqueous electrolytes. To overcome this challenge, most approaches have focused on improving the stability of Si by coating dense and thin protective layers using high vacuum-based techniques such as atomic layer deposition. However, these procedures are costly, making scalability for practical applications difficult. Herein, we report a modified electroless deposition （ELD） method to uniformly deposit protective and catalytic Ni films on Si wafers, resulting in efficient and stable Si photoanodes for solar water oxidation. The optimized Ni/n-Si photoanode achieves an onset potential of -1.09 V vs. a reversible hydrogen electrode and a saturation current density of -27.5 mA/cm^2 under AM 1.5 G illumination at pH 14. The ELD method is additionally capable of Ni deposition on a 4-inch n-Si wafer, demonstrating the first 4-inch Si photoanode. The solar water oxidation of the ELD-Ni/n-Si photoanode can be further improved by surface texturing, built-in n-p junctions, or coupling with more efficient catalysts.

Campylobacterjejuni in Musca domestica： An examination of survival and transmission potential in light of the innate immune responses of the house flies

引用

Insect Science 2017年第4期24卷 584-598页

作者： Carson gill Simon Bahrndorff Carl Lowenberger Department of Biological Sciences Simon Fraser University 8888 University Drive Burnaby BC Canada National Food Institute Technical University of Denmark 2800 Kongens Lyngby Denmark

The house fly, Musca domestica, has been implicated as a vector of Campy- lobacter spp., a major cause of human disease. Little is known whether house flies serve as biological amplifying hosts or mechanical vectors for Campylobacterjejuni. We in- vestigated the period after C. jejuni had been ingested by house flies in which viable C. jejuni colonies could be isolated from whole bodies, the vomitus and the excreta of adult M. domestica and evaluated the activation of innate immune responses of house flies to ingested C. jejuni over time. C. jejuni could be cultured from infected houseflies soon after ingestion but no countable C. jejuni colonies were observed 〉 24 h postingestion. We detected viable C. jejuni in house fly vomitus and excreta up to 4 h after ingestion, but no viable bacteria were detected 〉 8 h. Suppression subtractive hybridization identi- fied pathogen-induced gene expression in the intestinal tracts of adult house flies 4-24 h after ingesting C. jejuni. We measured the expression of immune regulatory （thor, JNK, and spheroide） and effector （cecropin, diptericin, attacin, defensing, and lysozyme） genes in C. jejuni-infected and -uninfected house flies using quantitative real time PCR. Some house fly factor, or combination of factors, eliminates C. jejuni within 24 h postingestion. Because C. jejuni is not amplified within the body of the housefly, this insect likely serves as a mechanical vector rather than as a true biological, amplifying vector for C. jejuni, and adds to our understanding of insect pathogen interactions.

Non-alcoholic fatty liver disease and the metabolic syndrome:Effects of weight loss and a review of popular diets,Are low carbohydrate diets the answer?

引用

World Journal of Gastroenterology 2006年第3期12卷 345-353页

作者： Harjot K gill George Y Wu Division of GastroenterologyHepatology Department of MedicineUniversity of Connecticut Health CenterFarmingtonConnecticutUnited States

Non-alcoholic fatty liver disease （NAFLD） encompasses a wide spectrum of fat-induced liver injury, ranging from relatively benign steatosis to cirrhosis and liver failure. The presence of obesity and insulin resistance is strongly associated with non-alcoholic fatty liver and confers on it a greater risk of histologically advanced disease. There is a growing concern in the medical profession as the prevalence of this disease continues to rise in parallel with the rise in obesity and the metabolic syndrome. Treatment options are limited and dietary weight loss is often advised. Low fat diets are difficult to adhere to and recent studies have shown the potential of low carbohydrate diets for weight loss and improving insulin resistance. Thus far, no study has evaluated the effect of low carbohydrate diets on NAFLD. Future studies will be required to address this question and others with regards to the nutritional adequacy and long-term side effects of these diets.
